Table 2. Paired analysis of normal new Ethiopian immigrants on arrival, their association with helminths, and the development of new allergen sensitizations after one year in Israel.

Change from normal	HI (+,+) n (%)	HI (+,-) n (%)	HI (-,-) n (%)	P value
Normal to SPT (+)	24 (30.4%)	6 (20.7%)	1 (5.6%)	0.075
Normal to allergic*	5 (6.3%)	2 (6.9%)	1 (5.6%)	0.98
Normal to non-allergic SPT (+)**	19 (24.1%)	4 (13.8%)	0	0.045

SPT (+): Positive skin prick test to one or more allergen (includes the allergic and non-allergic, asymptomatic sensitized atopic individual).

* Clinically symptomatic individuals with asthma and/or rhinitis, with a positive skin prick test (SPT+).

** Asymptomatic sensitized atopic individuals with SPT (+).

HI (+,+): 79 individuals infected with helminths on arrival and in whom the infection persisted after a year. 2^nd SPT was not done in 10 individuals.

HI (+,-): 29 individuals infected with helminths on arrival that were not infected after a year. 2^nd SPT was not done in 1individual.

HI (-,-): 18 individuals in whom no helminths were found on arrival and after a year.

P value: Chi square and Fisher’s exact test.
